The Multiquip 8982318980 Dosing Module is a genuine OEM component designed for DCA400SSI4F, DCA400SSI4F3, and DCA400SSI4F3PB super-silent diesel generators. As a direct OEM replacement, this part meets the exact specifications required by Multiquip for proper emissions system operation on these Tier 4 Final units. Sourced directly through authorized channels, the part ensures a correct, straightforward installation with no guesswork on fit or function. DHS Equipment carries this part to keep your DCA series generator running in full compliance and at peak efficiency.
Key Features
- Genuine OEM Metering Accuracy — Manufactured to Multiquip's exact dosing specifications, ensuring the correct volume of diesel exhaust fluid (DEF) is delivered to the aftertreatment system on every injection cycle.
- Direct-Fit Replacement — Engineered to connect directly into the existing DEF/SCR system harness and mounting points on compatible DCA series generators, simplifying the swap.
- Confirmed Fitment for DCA400SSI4F Series — Verified for the DCA400SSI4F, DCA400SSI4F3, and DCA400SSI4F3PB super-silent diesel-powered generator models.
- Emissions System Integrity — A properly functioning dosing module maintains correct NOx reduction across the SCR catalyst; a failed or stuck module triggers fault codes, derated output, or generator shutdown.
- Tier 4 Final Compliance — Replacing with a genuine OEM dosing module keeps the aftertreatment system operating within EPA Tier 4 Final emissions requirements, which is critical for permitted jobsite operation.
The dosing module is the precision metering component within a diesel generator's selective catalytic reduction (SCR) emissions system. Its job is to inject a carefully measured quantity of diesel exhaust fluid into the exhaust stream upstream of the SCR catalyst, where it chemically reduces harmful nitrogen oxide emissions before they exit the exhaust. When the dosing module fails — whether through clogging, electrical fault, or mechanical wear — the SCR system can no longer meter DEF correctly, leading to emissions faults, engine derating, or forced shutdown that takes the generator offline entirely.
